Document Summary
Focusing on the processes that allow the information stored in a gene to be expressed most genes code for proteins. Making an rna copy transcription has three major steps: initiation, elongation and termination not only making an rna, but also processing rna to get a mature rna (capping, splicing, 3" poly a) You have to get rna out of the nucleus and control mechanisms all processes involved in producing a functional rna. Transcription: there"s machinery or an enzyme that carries out the process has to bind to dna initiate synthesis and elongating and making rna molecules. Rna is doe not stay bound to dna molecule. Rna polymerases enzymes that bring about synthesis of rna. We already know one class of rna polymerase: primase. not involved in transcription. it just gets dna going by making small bits of rna. Rna polymerases are very similar in a lot of ways to dna synthesis precursors: ntps (as opposed to dntp)
